The asking price of property coming new to the market saw its usual seasonal fall at the start of December, but supply is getting tighter, Rightmove figures reveal.

The portal’s latest House Price Index showed values at £299,159, down 2.1% on November and with annual growth slowing from 4.5% to 3.4%.

Rightmove says this is in line with the average over the past six years.

Site visits in November were up 9% from 101m in November 2015 to 110m last month, feeding through to a 5.22% rise in sales agreed.

Rightmove says all regions except London are selling at higher levels than a year ago, with Yorkshire and the Humber experiencing the biggest rise at 15.4% followed by 13.3% in the North-East and 11% in Wales, while London is down by 7%.

But the portal warns that supply is failing to keep up with the increasing sales, with new listings only 2% above last year, meaning the average number of properties for sale per branch has fallen from 59 to 56 in a month, the lowest since March this year.

Average time to sell was 67 days, up from 65 in October and longer than the 60 days on average this time last year.

Looking ahead, Miles Shipside, Rightmove director and housing market analyst, predicted prices would rise by 2% in 2017, saying: “The price of property coming to market in 2016 is currently up by 3.4% compared to a year ago, so while a forecast rise of 2% in 2017 is a lessening of the pace, it would still be the seventh consecutive year of rising property prices.

“As well as prices moving out of reach for some buyers, the sword of Brexit uncertainty hangs over the market, an unknown factor that may – or may not – have damaging consequences for the economy and confidence.

“There was a bout of jitters with the unexpected referendum result, albeit now seemingly short-lived, but more may arrive after Article 50 is invoked.

“For the time being any nervousness is being over-ridden by high demand for the short supply of suitable homes for sale in the lower and middle market in many parts of the country.”
